Electro-dynamic vibrating test machine is mainly used for determining that the designed and manufactured machine and components are subjected to external vibration or self-generated vibration in the course of transportation and use without being destroyed, and exert their performance and reliability to reach a predetermined life. With the improvement of reliability requirements for products, especially aerospace products, the development of vibration test systems as the key equipment for reliability testing becomes more and more important.
Electro-dynamic vibrating test machine automatically positions the sweep frequency. Automatically adjust amplitude amplitude without stopping. The test frequency is adjustable. Easy to operate, reliable, and inexpensive. It is the ideal equipment for vibration resistance and reliability test of products in electric and electronic, instrumentation, household appliances and other industries.

This series power amplifier adopts modular design, single module output power up to 8KVA (a power amplifier box can accommodate up to 8 modules), supporting a variety of thrust electric vibration table.
Vertical extension table and horizontal slide
When the size of the test piece is larger than the size of the table of the electric vibrating table, the auxiliary vertical extension table and the horizontal slide table can meet the customer's requirements for the performance of the shake table and increase the installation area of the test attachment. Extended mesa materials can be made from lighter magnesium alloys or more economical aluminum alloys. The high-quality finishing casting process ensures that the extended table has a better strength-to-weight ratio and better frequency transmissibility.
Climate Tester provides users with complete horizontal slides, extended countertops and other ancillary products, users can make a one-stop supporting selection.
